You've been given all the tools necessary (and I assume you have class notes and a textbook as well). It's time you started using those tools - please show your work and clearly state where you're stuck.

complex numbers written in general as

right

then the argument of z given by

since the argument is values so to find theta values take arctan ( ) for both sides you will have

the argument of z denoted by arg(z)

note:- argument of z have infinitely many values

the principle argument of z denoted by Arg(z) is the unique value of such that as you can see the principle argument take one value

you can say that

n integar number

Examples:-

Find the argument and the principle argument to the following:

y=1 and x=sqrt{3} so

the tan is negative in the second quarter and in the third quarter but the principle argument take the values in the interval
